【Core Java】 The Java I/O System

I/O

 

1. 最common的用法，从一个文件按行读取数据。

public String getFileAsString(String path) {
		String fileAsString = "", sTemp = "";
		try {
			BufferedReader br = new BufferedReader(new FileReader(path));

			while ((sTemp = br.readLine()) != null) {

				fileAsString += sTemp;
			}
		} catch (FileNotFoundException e) {

			e.printStackTrace();
		} catch (IOException e) {

			e.printStackTrace();
		}

		return fileAsString;
	}
